Detectives have urged witnesses to come forward after a "brutal" sex attack on an 11-year-old girl.

The youngster is being treated in hospital after being grabbed by a man on her way home from school on Friday afternoon.

She was dragged in to Jubilee Park, in Enfield, north London, before being sexually assaulted near a pitch and putt course, Scotland Yard said.

The girl had caught a bus from Enfield town to Bury Street before she was snatched as she walked along Galliards Road at around 4.15pm. She eventually returned home after the attack at 7.45pm.

The suspect is described as a black male with afro hair wearing a dark grey top and black baggy jeans.

Detective Inspector Simon Ellershaw, who is leading the investigation, said: "This was a brutal attack on an 11-year-old girl on her way home from school and I am appealing for the public's help in catching the person responsible.

"We are interested in speaking to anyone who was in the Jubilee Park area between 4.15pm and 7.45pm on Friday evening, November 23, and may have seen anyone acting suspiciously or anyone following a girl in school uniform."

Any witnesses or anyone with information that could assist police should call the incident room on 0208 345 4326 or call Crimestoppers anonymously on 0800 555 111.
